碩士 === 國立成功大學 === 工程科學系 === 104 === With the rapid development of cognitive radio (CR), several security issues have drawn a lot of attentions. Among them, the detection of primary user emulation attacks (PUEA) is the most critical one. In this work, we proposed a method by using the characteristics of wireless channels, i.e., channel-tap power, to identify the PUEA. In order to verify the performance of our design, we implemented the proposed algorithm by the register-transfer-level (RTL) model, and verified it by the OFDM system on Wireless Open-Access Research Platform in real radio environments. We evaluate the effects of the distance, angle, and the line of sight propagation between the transceiver and receiver on the proposed channel-tap power signature. Also, the influences of SNR and the number of symbols on the detection probability are analyzed.
